Definitions

  • the present invention relates to the insulation of the walls of a room using air circulation along the wall, a technique known as "parieto-dynamic insulation” and more precisely that which uses the Coanda effect to circulate the air along the wall.
  • Thermal insulation of rooms of the parietodynamic type conventionally consists in passing air between two walls of the neighboring room, generally parallel to one another. This air is taken outside and, by entering the room, serves to renew the atmosphere.
  • the document WO 87/01155 provides for installing a third wall parallel to the first two which thus makes it possible to lengthen the path followed by the air.
  • the glass wall directed towards the interior of the room is heated and the parieto-dynamic system thus participates in the heating of the room.
  • the set constitutes a triple window which is additionally equipped with a blower.
  • the invention therefore provides a method of thermally insulating an outer wall of a room by circulating air from bottom to top between said outer wall and an inner heated wall such that the air undergoes additional heating beforehand, in which the heated air circulates from the top of the heating wall by Coanda effect thanks to a deflector directing the air streams which come from it along the internal surface of the heating wall.
  • the interior heating wall includes as a heating element, a conductive layer.
  • the walls are made of transparent materials such as glass and the conductive layer is thin, transparent or semi-transparent.
  • the conductive layer is advantageously in contact with the air flowing from bottom to top between the heating interior wall and the exterior wall, it has an emissivity of less than 0.40.
  • the invention relates to a device for the pareto-dynamic insulation of a room comprising two walls designed so as to allow the circulation of air from bottom to top between the outer wall and the inner wall which is heated, the air outlet being carried out towards the interior of the room, in the upper part of the heating wall, device which includes a Coanda deflector which directs the air streams which come from it along the internal surface of the wall heating.
  • the means for heating the latter is preferably a resistant, transparent or semi-transparent thin layer. It advantageously belongs to the following group: layer which comprises metal oxides obtained by pyrolysis of organometallic compounds in particular pulverulent, metal layer in particular of silver, set of layers comprising at least one layer of metal.
  • the layer is obtained by pyrolysis of a product based on organometallic salt so that it comprises a tin oxide doped with fluorine.
  • FIG. 1 schematically represents an air inlet mouth which allows the renewal air to run along the internal surface of a wall.
  • Figure 2 shows the combination in a single window of two parieto-dynamic effects, that of the double wall and the Coanda effect.
  • Figure 3 shows a window tester
  • FIG. 1 which represents the adaptation of the Coanda system to the parieto-dynamic insulation
  • a wall 1 for example made of glass, mounted in a frame 2 by means of a sealant which remains plastic 3 and a glazing bead 4 fixed by means not shown.
  • An air inlet 5 allows the outside air intended to renew the atmosphere of the room to enter it under the action of a pressure difference generally obtained by a central suction system which acts most often on several premises, all parts of a dwelling for example.
  • the originality of the Coanda system known per se, lies in the design of the deflector 6 made of sheet metal or plastic, it channels the admitted air over the entire width of the panel 1. This deflector ends in a slot 7 and in a narrow passage 8. The air streams coming from passage 8 run along the surface 10 of the wall 1.
  • FIG. 2 elements of a system according to the invention are presented.
  • a plastic window 11 with its opening 12 and its seals 13, 14. It is equipped a single glazing 15 mounted with seals 16 and a glazing bead 17 on shims 18.
  • This opening is equipped with a glazing 19 carried by profiles 20, it can be opened to allow cleaning of the internal faces of the glazing.
  • a deflector 21 has been fixed - removably to allow the operation of the glazing 19 - which makes it possible to obtain a Coanda effect on the face 22 of the glazing 19 directed towards the interior of the room.
  • This system is of the same type as that of FIG. 1.
  • the novelty here resides in the fact that the air, before entering at 23 into the deflector 21 has circulated from bottom to top in the space between the glazing 15 and 19. Previously, the air has passed through the orifices 24, 25 formed in the sections of the opening. As before, the movement of the air, a first time from bottom to top between the two panes 15, 19 and a second time, from top to bottom along the surface 22 is obtained by the action of a central ventilation system. which puts the whole room in slight depression compared to the outside.
  • the invention provides that the glazing is equipped on the internal face of its inner glass 19 with a thin transparent conductive layer, not shown, supplied with electric current by current leads.
  • the layer consists for example of metal oxides obtained by pyrolysis of powdery organometallic tin salts deposited on the hot glass according to the process described in French patent FR 2 427 141.
  • the heated glass is then "licked" twice by the current of fresh outside air, once from bottom to top in the space between the two panes and a second time from top to bottom by Coanda effect.
  • the double passage of air makes it possible to significantly decrease the temperature of the heated glazing for a given electrical power, which makes it possible to maintain significant comfort and efficiency despite a calorific contribution, itself considerable. This allows, in many cases to have as the only means of heating the room, the heated window.
  • FIG. 3 shows the installation used. It has a double enclosure, the outer enclosure 39 being separated by a guard ring 40 from the inner enclosure 41. All the walls are insulating. The interior enclosure is separated into two parts by a partition 42 comprising the window to be tested 43, the latter whose overall dimensions are 1.50 mx 1.05 m is successively equipped with four different systems: firstly a combination of the type of FIG. 2 in which the Coanda deflector 21 has been removed and where the outside air has been passed directly through the top crossmember. However, this window has been fitted with a glazing 19 which is heated (Test I). The second combination is identical, but with Coanda deflector.
  • the third variant is a heated window with air circulation from bottom to top in the double wall but without Coanda effect (the deflector is removed, Test III).
  • the fourth variant it combines heated glazing, circulation in the wall and Coanda effect (Trial IV). It is this which is represented in FIG. 3.
  • the right part 44 of the interior enclosure is isothermal at 7 ° C., its temperature is kept constant thanks to the combined effects of an evaporator 45 which operates continuously. and a heating resistor 46 which, thanks to proportional regulation, stabilizes the temperature ambient.
  • a heating resistor 48 makes it possible, when desired, to regulate the ambient temperature on this side too, but at 20 ° C., this time.
  • test campaigns For each of the four test campaigns (I, II, III, IV), we started by stabilizing the temperatures in the two rooms 44 and 47 at 7 ° C and 20 ° C respectively, this stabilization continued for one hour and thirty minutes. At the end of this period, the resistor 48 was disconnected while the regulation continued to operate in room 44. The test campaign then started by switching on the heating of the heated glazing subjected to an electrical power of 600 Watts, the measurements being carried out, here, after stabilization an hour and a half.
  • the air movements at his height will be less important and moreover, as on the one hand, the temperature of the internal wall is slightly higher in the test IV than in test II and like on the other hand, the surface not cooled by the Coanda effect is larger, the overall effect produced by the thermal radiation of the wall will be significantly stronger and the sensation of heat greater.
